"A cold front will continue to advance eastward Thursday into Thursday night bringing a threat of severe thunderstorms from the upper Ohio Valley to the Gulf Coast and the Carolinas. Damaging straight-line winds in excess of 60 mph, large hail and a few tornadoes are possible," warns The Weather Channel.

South Dakota's Argus Leader says that "tens of thousands of residents in southeastern South Dakota remained without power Wednesday as they hunkered down for the second wave of a record-setting winter storm that already downed power lines, snapped large trees and closed roads, schools and businesses."

"Another round of severe weather is expected for Thursday across the eastern Ohio and Tennessee River Valleys as well as the southern Mid-Atlantic and Southeast U.S. The primary threats will be damaging winds, tornadoes and large hail. At this time, it appears the greatest risk may be focused across portions of Alabama, Georgia and the Florida Panhandle.
